Answer:
180-90=90
90÷2=45
answer is 45
Step-by-step explanation:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Answer:
4√3 feet
Step-by-step explanation:
Here, a ladder is resting against a house makes a 60° with the ground,
Consider x be the distance of the top of ladder from the foot of house and y be the distance of bottom of ladder from the house. ( shown in the below diagram )
Using trigonometric ratio,
We have, length of ladder = 8 ft,
Hence, the house would reach 4√3 feet up.
Answer:
The measure of the length is
Step-by-step explanation:
Let
x-----> the length of rectangle
y-----> the width of rectangle
we know that
The perimeter of rectangle is equal to
so
Simplify
-----> equation A
----> equation B
Substitute equation B in equation A and solve for y
Find the value of x
So you can solve this by drawing a digram. Draw each points and label all checkpoints. Study the drawing as long as you can to understand the situation. The question is asking for too much, so its a slippery slope.
